By the way it is Overwatch and Errortrap that will both tell you about stuck sims, but I have to tell you Overwatch has been tossing stuck sims issue needlessly since SN. I finally took it out by the time I tried the last version and it was still doing that - as it makes things worse when it constantly resets sim. Using reset all the time can cause corruption in the hood if overused. But that is the way Overwatch handles things. It just resets everything that don't jump fast enough for it. I think it is a bit overtuned. Because sims foot tapping while others block their way is not REALLY a stuck sim, but overwatch will treat it as it is. If I had overwatch in it would have sent that horse home, when it was not needed at all. It is asking for game corruption when it does that so often over actual issues that will fix them selves if allowed the time. I saw overwatch whoosh a kid home when a dad put the kid down so he could give it a bottle. Not cool!! Errortrap can be even worse in the fact it will actually alter the script and that is not a good idea. So for all the good those mods do, they can also end up causing worse corruption in a world eventually. So I use IW very sparingly and not at all since I saw what it was doing in SN. I tried up to version 78 and it was constantly tossing up stuck sims warnings - the sims were not stuck. I saw that when I was at the very place it said there was a stuck sim and the sim in question was waiting to use the bathroom. OW has to be tuned to differeate sims waiting from something from actually being stuck. Unfortunately ea makes that hard as Sims throw the same routing error when they can't get to what they need or want immediately as they do if the path is blocked or they are stuck. But I assure you none of the sims were actually stuck.
